I'm surprised that space stuff doesn't do well. I like space stuff a lot.

The cost of Hubble: $9bn
The value of Hubble: Infinite

I can confirm its effectiveness in inspiring future generations.

Born in 1997, grew up looking at pretty space pictures.
In 2010 I decided I wanted to look at and think about space for my entire life.
I now have a master's degree in astrophysics, and desperate to get accepted to an astrophysics PhD programme.

Thanks Hubble

I wonder if we’ll see a megaproject on the Voyager probes one day.

[nicosmind]

I hear theyre replacing the Hubble in the year 3022, after James Webb is finally finished

[roshambo]

Do my dad's new front porch. He's way over budget and it's not even finished yet..

"Is it important to know about this?"
It might be. We don't know. That's the point.
Was a study a few years ago on sea slugs. Who cares about sea slugs, what good could come from such a study? Well, a new heart medication and two cancer treatments. Among other data.

I’m amazed it was never mentioned that many of the colors in those incredible photos are not “real”.

The wavelengths are real; however, a massive part of the photo processing is artistic. It’s not done for science, but it’s done for publicity. The scientists don’t look at those colorful images. They look at the different specific wavelengths they’re interested in.

Humans have no perception of what X-Rays, microwave, infrared, UV wavelengths look like, because those are not in our visible spectrum. Those wavelengths, we normally can’t see, are given false representations when the images are stacked from Hubble.

Aww... Simon totally skipped over what actually went wrong with the mirror! The company that ground the mirror had, of course, equipment to measure the dimensions of the mirror being produced. NASA decided that they needed to build a special testing tool to verify the dimensions and qualities of the mirror in a different way. The original equipment indicated that they were right on target and the mirror was perfect, but the specialty equipment from NASA reported that the shape was wrong... So they trusted the NASA tool of course. But... Obviously, . it was the NASA tool that was wrong.

The fix, COSTAR, was basically just an image processing unit that was, thankfully, able to correct the small issue with the mirror.

My dad actually was a part of the Hubble project. There are parts on it that he designed. He has since passed away and I really miss all the stories he told me and reading the articles he posted in a lot of magazines. RIP Dad and I hope you’re getting to see your work up close again.😢

What I learned from today's episode: The Hubble Space Telescope wears corrective spectacles. 😁😁

[MeijndertMotorsport]

Suggestion: The "Maasvlakte I & II" land reclamation projects in the Netherlands.

This was a great video. Would love to see the James Webb telescope and what we have of it so far.

[silenttoxic]

After sooo many comments the Hubble Space Telescope 🔭 Megaproject video! Thanks Simon

[cikame]

The details behind the mirror being flawed is the most amazing space story to me, and the fact that they managed to fix it and make it work is just incredible.

[fredflintstone]

Simon remembers the Hubble going up, I remember Skylab coming down.

[bencushwa]

Hubble's mirrors were perfectly manufactured to an imperfect design specification.

Measure twice, cut once....

Simon: "It all sounds 'super logical.' "
Spock sees what you did there.

Well done. I’m an amateur astronomer who’s long followed the Hubble closely & knew most of the history. That was as good of a concise description of the history of the development as I’ve seen. Most of the NASA related videos focus more on promoting the Hubble than explaining the history.

Interestingly enough I have a special keychain that was issued by Perkin Elmer, the maker of the mirror & OTA that had so many early issues, in the early 80’s before the launch. I still have all the original packaging. The pamphlet that is inside goes on at length about the upcoming 1984 launch, which of course did not happen BECAUSE of Perkin Elmer. That keychain is probably worth something now, but I’ve never checked. It’s one of those things I enjoy having

James Webb seems to be doing its best trying to out delay hubble. A fitting replacement i guess
